Subject: [PATCH] wasm: fix FinalizationRegistry logic for Cloudflare Workers
This patch fixes FinalizationRegistry related logic for Cloudflare
Workers in wasm backend js post linker. Cloudflare Workers doesn't
support FinalizationRegistry, in this case we use a dummy
implementation that doesn't do anything.
(cherry picked from commit bea8ea4cabcd51d098a361bd27d78884effa5d00)
